From the Times today. You may discuuss. Navy jet switch to save Â£10bn The Fighters would have been the most expensive single project in the defence budget, with costs already put at Â£13.8 billion and rising Michael Smith Published: 1 August 2010 The Joint Strike Fighters, costing Â£100m each (HO/AFP/Getty Images) The Royal Navy is set to save Â£10 billion on the defence budget by dropping plans to buy a fleet of fighter jets costing Â£100m each for its new aircraft carriers. It is expected to swap an order for 138 Joint Strike Fighters (JSF) for a version of a cheaper aircraft currently flown off US carriers, the Boeing F/A-18 Super Hornet. The cost-saving move was considered at a meeting last weekend between Liam Fox, the defence secretary, and services chiefs to discuss cuts. â€œJSF is an unbelievably expensive programme,â€ said a senior defence source. â€œIt makes no sense at all in the current climate, and even if we continued with it we cannot afford the aircraft we said we would buy.â€ The JSF, built by Lockheed Martin, Boeingâ€™s main American rival, would have been the most expensive single project in the defence budget, with costs already put at Â£13.8 billion and rising. The aircraft were set to replace Harrier jump jets flown by the RAF and Navy.
